Back in the day where the microprocessor was our standard building block, we tended to concentrate on computation and processing of data and not so much on I/O. Simply put there were a lot of things ...

In previous installments of the AudioFile, we've talked about basic PCM audio, which encodes audio into a series of numbers that a computer can play or manipulate. We've also discussed the process of ...

Did You Know? The “real” world we are living in is Analog! Whether it is sound, light, temperature or humidity, all are continuously varying things. However, when we want to communicate with the ...

While we all went through intensive course work in engineering school studying analog-to-digital converters (ADC), operational amplifiers (Op Amp), digital-to-analog converters (DAC) and other ...

Designers of digital systems are familiar with implementing the 'leftovers' of their digital design by using FPGAs and CPLDs to glue together various processors, memories, and standard function ...

All analog-to-digital converters (ADCs) have a certain amount ofinput-referred noise. In most cases,less input noise is better. There are some cases, however, where inputnoise can actually be helpful ...

Making sound with digital logic usually calls for a Digital to Analog converter. Building one can be very simple, and the sound quality out of an R-2R Ladder is actually pretty good. In the last ...
